  • Patent number: 9855965
    Abstract: An infant carrier includes a carrier frame, a wheel, and a vibration dampening device disposed therebetween. The vibration dampening device includes a first vibration dampening part, a second vibration dampening part, and an actuator. The first and the second vibration dampening parts are disposed between the carrier frame and the wheel. The actuator is movably disposed on the carrier frame or the wheel. The releasing position has a releasing position and an enabling position for adjusting an action range of the second vibration dampening part moving to the actuator. Therefore, the action range can be adjusted by adjusting the position of the actuator for making an vibration dampening effect performed by the first vibration dampening part or by the first vibration dampening part together with the second vibration dampening part, so that the infant carrier can adapt to different road conditions by adjusting the vibration dampening device through the actuator.

  • Publication number: 20100230925
    Abstract: A four wheeled, human-powered, striding cycle that uses the stepping and striding motion of the human legs to propel a rider forward. Two separate and dependent foot pedals are moved fore and aft along a concaved arc segment. The motion simulates the natural stepping and striding motion of a running human. A standing human steps on a pedal, then moves it down and aft in a striding motion. As one pedal is moved aft, the other pedal moves forward in a reciprocating fashion. A cable and pulley system connects each pedal with its respective rear wheel. Pedal motion aft applies torque to its respective drive shaft which in turn rotates its respective drive wheel. Pedal motion forward also provides torque to the opposing drive shaft creating additional torque for the opposite wheel. Forward motion begins when force is exerted down and aft on each pedal by the stepping and striding motion of the human leg.

  • Patent number: 7588110
    Abstract: Disclosed is a three-wheeled vehicle with centrally positioned motor and driver's seat. An exemplary embodiment has a frame for supporting a driver and a multitude of mechanical devices. A pair of steerable front wheels are rotatably affixed to the front portion of the frame. A rear wheel is rotatably affixed along the frame's centerline in the rear portion. A motor is affixed to the frame's centerline. The driver's seat is also affixed to the frame's centerline behind the motor and ahead of the rear wheel, so the driver sitting in the driver seat is in both a recumbent and straddle position.

  • Patent number: 7552934
    Abstract: A pedalling vehicle includes a main body, two control handles, two drive links, and a transmission link. The main body includes a front frame a front wheel, a rear frame, two rotation devices, two rear wheels, two cranks, and two connecting members. The rotation devices are connected by the transmission link through connection of the connecting members so that the rotation devices are rotatable synchronously and the rear wheels are movable with the rotation devices synchronously. Thus, the two rear wheels are turned synchronously by connection of the transmission link so as to turn and change the travel direction of the pedalling vehicle exactly.

  • Patent number: 7540517
    Abstract: A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.

  • Publication number: 20090058037
    Abstract: The present invention relates to a balance compensation apparatus to be used by persons with one dysfunctional leg and one operative leg. In particular, the invention relates to an apparatus with a frame having at least one lateral support with an aperture for slidably engaging a kneeling platform assembly and a steering column that is mounted on the frame to be offset from a longitudinal centerline of the frame. A handlebar is connected to the steering column. The platform and the handlebar are adjustable for added comfort, control and stability. The platform assembly may be offset of the longitudinal centerline to a side in common with the steering column and have cushions for added comfort. A hand brake may provide stability and safety and the steering column may fold for easy storage.

  • Publication number: 20080191447
    Abstract: A human powered vehicle of the pedal-driven type having four wheels, a composite monocoque chassis, four wheel independent suspension, and seat for supporting one or more occupant/driver/riders in a generally supine position, and an aerodynamic chassis enclosure with a transparent canopy which is openable for entry and egress of the rider. The preferred embodiment for a single rider has two steerable wheels located forward of the rider, and two fixed drive wheels positioned behind the rider. The drive wheel is equipped with a multi-sprocket gearing arrangement, and a large pedal-equipped sprocket wheel is mounted in a position slightly forward and above the common axis of the front wheels for the rider's feet. A single drive chain extends from the drive sprocket to the sprocket cluster and passes under/over idler rollers which direct the chain beneath the rider.

  • Publication number: 20080164085
    Abstract: The necessity to get higher degrees of safety through better stabilities of the “Scooter-Cyclemotor-Bicycle-Motorcycle” has made these 2 kinds of assemblies (front and rear). The Front assembly always has forwarding the “2 steering, inclining, shock-absorbing, braking, parallel front wheels” and with the already existent 1 rear-wheel in the rear side, or with the Rear-assembly, that has the “2 inclining, shock-absorbing, braking, parallel rear-wheels” (Page: 1,2,3,4,5,6,7./7). Those 2 kind of assemblies are singularly, or both, suitable to build a vehicle with ‘3, or 4 wheels ’ (with 2 rear-wheels), always determining 3 or 4 points of contact on the ground (not only 2). The vehicle with ‘3, or 4 wheels’ is safer, it's more vertical steady and answers the highest degrees safeties either, with a second passenger on board, or with major loads upon (like heavier accumulators use for electric or hybrid power and/or if it uses major load-structures like new body carriage).
